Headband assemblies for over-ear noise-cancelling headphones · Length adjustment with sliders and detents, ear-cup rotation, force on the ear, the cord routed between the two ear cups, and why fit decides how well active noise cancelling works
A headband assembly is the arched structure that joins the left and right ear cups of over-ear headphones: a padded band or cushion assembly, a slider at each end that sets the length, hangers or yokes that let each ear cup turn to the ear, and the cord that carries signals and power from one cup to the other. In noise-cancelling headphones it also decides whether the ear pads seal around the ear, which the microphones and cancellation circuit depend on. Ask three things first: how the length is adjusted and held, how the cord passes through the moving parts, and what fit and force the finished headset must achieve.
Headband assemblies (band, cushion, sliders, detents, hangers or yokes, internal cord) for over-ear wireless and wired noise-cancelling headphones, and the fit requirements they place on the finished headset. Drivers, ear-cup electronics, batteries and the noise-cancelling processor are described only where they affect the headband.

Set length adjustment, ear-cup orientation and force on the ear
In Sony's WH-1000XM5 help guide the headband carries a slider at each end that is slid to adjust its length. The wearer extends the sliders fully, puts the headset on, shortens the sliders until the headband touches the top of the head, then turns the left and right units so the earpads fit snugly all around the ears. Sony warns that if the slider is not adjusted the headset may sit badly, causing discomfort or a weak noise-cancelling effect, and the wearing-detection sensor may stop playback or switch the headset off. [2][1]
Patents show how the length setting is held. A Turtle Beach patent uses headband slides that move vertically inside the ear cups and are held by ball detents, a metal or plastic ball on one part engaging holes in the other; headband pivots give the ear cups rotation, and the patent states that the shape and rigidity of the headband and slides set the force on the ear, with a sliding metal or rigid-plastic strip that raises rigidity and so raises that force. A Bose patent describes a cushion assembly with flat-tube sliders made of two mated plastic parts, and a spring heat-staked inside the headband that rides on a hub to give controlled friction and to define stowed and deployed detent positions when the ear cups fold. [7][6]
The headband carries the whole headset: Sony lists the WH-1000XM5 at approximately 250 g, operating at 0 °C to 40 °C. [3]
Give the supplier the headset mass and ear-cup geometry, the head-size range to fit, the target force on the ear, the adjustment mechanism (detent, friction or ball detent) and number of positions, fold or rotation requirements for the yokes, the surface and padding material, and the durability cycles expected for sliding and folding.
02
Route the cord through the sliders and keep noise cancelling working
A Sony patent describes the cord running between the left and right housings to carry drive current to the driver in the far housing. It explains that a cord exposed beside the slider may break from shock or catch on other parts, and that bending the spare length into a U shape inside a slider case needs a long case or the cord is too short when the slider is drawn out. Its solution coils the cord inside hollow cylindrical sliders so the coils stretch and compress as the length changes. A Bose patent runs the cable through both sliders and the cushion assembly, keeps slack on each side of a retention point near the earphone end, and uses a rigid loop on the yoke to push the cable back into the slider when the ear cups unfold. [5][6]
Sony's parts guide places noise-cancelling microphones inside and outside both the left and right units, with a built-in Bluetooth antenna; its noise-cancelling function generates antiphase sound against outside noise, "works primarily on noise in the low frequency band such as vehicles and air conditioning", and may lose effect or produce a feedback beep depending on how the headset is worn. [1][4]
A Dartmouth study explains why fit and the two microphone positions matter: passive attenuation of a circumaural earcup is minimal at low frequencies, feedback control from an internal error microphone gives 10–20 dB over 50–400 Hz for stationary broadband noise, and a hybrid system that adds an external reference microphone gave 5–30 dB active reduction for tonal noise and 18–27 dB for nonstationary noise at 50–800 Hz, improving performance below 100 Hz by up to 15 dB, with 30–40 dB total attenuation. The error microphone sat about one inch from the concha. [8]
Ask for the cord construction (conductor count, coiled or straight), how slack is stored at full extension and when folded, the flex-cycle test on the cord, and confirmation that the assembled headset keeps the ear pads sealed around the ear across the head-size range.

Buyer questions
How does a headphone headband adjust its length?
Sliders at each end move in or out; patents hold the position with ball detents, friction or spring detents. [1][7][6]
Why does headband fit affect noise cancelling?
Sony warns that an unadjusted slider can give a weak noise-cancelling effect because the earpads do not sit properly. [2]
How does the cord pass through an adjustable headband?
It runs through the sliders and band with stored slack, for example as a coil inside hollow sliders or a retained loop. [5][6]
How much does hybrid active noise control reduce?
A Dartmouth study measured 5–30 dB for tonal noise and 18–27 dB for nonstationary noise at 50–800 Hz. [8]
Sources and what still needs a direct check
